Albert W Kovalick: Method and apparatus for enhancing and maintaining character quality in thermal printers. Hewlett Packard Company, F David LaRiviere, January 27, 1976: US03934695 (35 worldwide citation)

The quality of thermally printed characters is enhanced by controlling the time at which and the time for which power is applied to the resistive printing elements in a battery-operated moving-head thermal dot matrix printer. By sequentially strobing the elements in the pattern of the character to b ...

Roland Hassun, Albert W Kovalick: Waveform synthesis using multiplexed parallel synthesizers. Hewlett Packard Company, Edward Y Wong, June 12, 1984: US04454486 (34 worldwide citation)

A novel signal synthesizer provides high frequency synthesized waveforms for the user. By converting phase information into digital outputs in parallel and by selectively coupling these digital outputs, an ordered digital output is formed to provide the high frequency waveforms. This ordered digital ...

Albert W Kovalick: Apparatus and method of phase-to-amplitude conversion in a sine function generator. Hewlett Packard Company, Edward Y Wong, November 13, 1984: US04482974 (22 worldwide citation)

A sine wave generator uses a phase-to-amplitude converter (PAC) which functions with a novel multiplier. By using pipelined adders, intermediate amplitude and slope data from storage are combined to get an output amplitude which is equivalent to that from a prior art multiplier but without the objec ...

Albert W Kovalick, Roland Hassun: Digital synthesizer with phase memory. Hewlett Packard Company, Edward Y Wong, January 28, 1992: US05084681 (10 worldwide citation)

In direct digital synthesizers in the prior art, the output signal maintains a phase continuity whenever it switches, or hops, frequency. This phase continuity shows up as a smooth change in phase from one frequency to the next; the phase of the last frequency transitions into the phase of the new f ...
